C. Statement-I is True, Statement-II is False.
D. Statement-I is False, Statement-II is True.

Answer

To solve the question regarding the statements about vinylic halides and their reactivity towards nucleophilic substitution reactions, we will analyze each statement step by step.

### Step 1: Understanding Vinylic Halides
Vinylic halides are compounds where a halogen atom (X) is attached to a carbon atom that is part of a carbon-carbon double bond (C=C). The general structure can be represented as CH2=CH-X.

### Step 2: Evaluating Statement I
**Statement I:** "Vinylic halides are reactive towards nucleophilic substitution reaction."

- Vinylic halides are generally less reactive towards nucleophilic substitution reactions compared to alkyl halides. This is because the carbon-halogen bond in vinylic halides has a partial double bond character due to resonance. The presence of the double bond and the resonance stabilization makes it more difficult for the nucleophile to attack the carbon atom bonded to the halogen.

**Conclusion for Statement I:** This statement is **false**.

### Step 3: Evaluating Statement II
**Statement II:** "Reactivity is due to the polarity of the carbon-halogen bond."

- The carbon-halogen bond in vinylic halides is indeed polar due to the difference in electronegativity between carbon and halogen. However, the polarity alone does not make vinylic halides reactive towards nucleophilic substitution. In fact, the resonance and the partial double bond character make the bond stronger and less reactive.

**Conclusion for Statement II:** This statement is **true**. The bond is polar, but it does not enhance the reactivity of vinylic halides toward nucleophilic substitution.

### Final Conclusion
Based on the evaluations:
- Statement I is **false**.
- Statement II is **true**.

Thus, the correct option is **Option 4: Statement 1 is false but statement 2 is true**.
